Twitter increasing GIF size limit
This change only applies to the web version of Twitter; on mobile the limit is still 5MB. Twitter’s support page reads, "Photos can be up to 5MB; animated GIFs can be up to 5MB on mobile, and up to 15MB on web.”
This is the latest in a series of welcome changes that Twitter is making. It recently excluded additional elements like usernames, images, and polls from its 140-character limit. Meanwhile, in July, it started supporting videos of up to 140 seconds in length.
